Summary

This study looked at whether showing children pictures of healthy teeth or decayed teeth helps them learn to brush better. Sixty kids aged 7 to 14 received hands-on brushing lessons, some with positive images, some with negative images, and some with no images. Researchers measured plaque and bad breath before, one week after, and one month after the lesson to see which method worked best.
